'Specification of Letters Patent.

Patented May 25, 1915.

T0 all whom t ymay concern Be it known that I, FRED T. RICHARDS, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of llinois, have invented certain new and useful Improvements in Scales, of which the following is a specification.

The object of my present invention is to provide a scale improved in various respects hereinafter appearing; more particularly, by providing a scale-beam therefor carrying an indicator which shows both the weight and another property, as the value, price, shipping cost, etc., of the commodity weighed, and having an indicator movable thereon to desired convenient positions for observation; by providing a scale-beam having interchangeable indicators; by providing a counterpoise for the scale-beam having a hair pointer; by providing a scale-beam having indicator markings arranged in rows longitudinally of the beam, and a counterpoise therefor having markings correspondingly arranged in columns; by providing a scale-beam having automatically relatively adjustable bearing members; by providing a scale-beam having an improved balance-adjusting device; and further, by providing such parts and devices in various combinations. These and other objects appearing hereinafter are attained by, and the invention finds specific embodiment in, the structure hereinafter described and illustrated in the accompanying drawings, in which- Figure 1 is a side view of my scale, ar ranged as a postal scale. Fig. 2 is a like view, slightly modified and showing another adjustment of the beam. Fig. 3 is a rear vview of a fragment of the scale-beam and its indicator frame. Fig. l is a vertical section of the indicator frame and plate taken on line B-B of Fig. 3. Fig. 5 is a section of the counterpoise taken on a plane corresponding with line A-A of Fig. 1. Fig. 6 is a face view of one of the indicator plates. Figs. 7 and S are vertical central sections of lthe scale-beams bearings 1 and 2 respectively. Fig. 9 is a front view of the me1n ber 5 of either of these bearings, with fragmentary connected parts.

In the construction illustrated, each of the oscillatory bearings 1 and 2 of the scale beam 3 comprises a fulcrum or knife edge member l and its complementary member 5,-in the form shown a sleeve on whose inner surface the member 4i bea-rs, and whose outer surface is curved in longitudinal section, its diameter diminishing toward its ends, whereby it is permitted to have a slight oscillatory movement in the plane of such section in its socket 6, so that said member may automatically adjust itself to the edge of the other member i along the length of such bearing edge. A spline 7 engaging in the groove S may be provided to prevent the sleeves rotation, and the sleeve may be securely retained in its socket by a stop 9 and a pivoted member 10 which also serves as a closure for the outer end of the bearing.

To the scale-beam 3 is pivoted, on an aXis 11 extending longitudinally of the scalebeam, an indicator comprising an indicator frame 12 and indicator plate 13, adapted to be turned or tilted on the aXis 11 to a desired position convenient for observation. This pivotal connection may comprise the circular disk portion 14C of such frame engaging within the arcuate flange portion 15 of the scale-beam, and also the tightening spring 1G interposed between the connected parts, whereby an easily movable, yet secure and durable swivel joint between such beam and frame is provided; the axis 11 being a threaded bolt, the tension of the spring may be readily adjusted thereby.

The indicator frame is adapted to hold in the position thereon for correct weighing, the indicator plate 13. As illustrated in Fig. 6, this plate may show not only the weight but also another property, as the value or price, of the commodity being weighed. To insure the correct positioning of the indicator plate on the frame 12, as well as to attach it thereto, it may be formed with ears 17 adapted to be bent backwardly and then thrust through registering slots or orifices 18 in said frame. It will be seen that inasmuch as these plates are attachable to and detachable from said iframe, several having different markings may be made interchangeable, so that by using an indicator plate, showing, for instance, weights and prices (as illustrated in Fig. 6), and then another (as that appearing in Fig. 1 showing the postal rates), the same scale may be used for more than one specific purpose. The indicator frame may be formed with rearwardly extending strengthening flanges 19 as shown. The upper edge 20 of this frame is not notched, but the sliding counterpoise 21 runs smoothly thereon, so that it may be precisely adjusted to any of the markings shown in any of the various rows of markings on the indicator. The tace of this counterpoise displays markings 22 arranged to correspond to the several roivs of markings appearing on the indicator, whereby the roivs may be readily and certainly identified While the .veiUhing is being observed. The counterpoise is provided with a hair pointer 23 so that the indicator may at a glance be seen on both sides of such pointer, to facilitate the easy and accurate reading of its markings. rlhis hair pointeigka slender iviremay be carried by the detachable face plate 24 of the counterpoise, which plate securely holds the counterpoise in its sliding engagement on the indicator frame, said frames longitudinal flanges 19 entering and sliding in grooves 25 in the counterpoise, as shown in Fig. 5.

Un the scale-beams screw-post 26, extending longitudinally thereof, is threaded a balance-adjusting nut 27, shoivn in Fig. 3. This nut is split transversely of its axis to form a body portion 28 and a locking portion 29; a screw 8O passing through one said portion and threaded in the other, serves to spring the locking portion toward the body portion of the nut, thus to securely bind or lock the nut in its adjusted position on the screw post.

rlhe operation or' the invention clearly'appears from the foregoing description.

Not confining myself to details of construction shoivn, the invention being manifestly capable of embodiment in varying forms, l claim:

l. ln a scale, a scale-beam, and an indicator pivotally connected thereto on an axis extending longitudinally of the scale-beam, one of said connected parts having an ex- Gopies of this patent may be obtained for :ve cents each, by addressing the Commissioner of tended disk bearing and the other of said connected parts having a complementary bearing with an arcuate Hange engaging the edge of said disk bearing.

2. In a scale, a scale-beam, and an indicator pivotally connected thereto on an axis extending longitudinally of the scale-beam, one of said connected parts having an extended disk bearing and the other of said connected parts having a complementary bearing With an arcuate flange engaging the edge of said disk bearing and a tightening spring interposed between said connected parts.

8. In a scale, a scale-beam having perforations, a counterpoise thereon, and an indicator plate having ears adapted to engage said perforations and to be bent into supporting position to hold the indicator in predetermined viixed relation to the scale-beam.

4. In a. scale, a scale-beam having a longitudinally extending screw-post, a balanceadjusting nut threaded on said post and split transversely of its axis to form a body portion and a nut-locking portion relatively movable, and means for moving the locking portion relatively to the body portion to lock the nut against turning movement on the post.

5. In a scale, a scale-beam having a longitudinally extending screw-post, a balanceadjusting nut threaded on said post and split transversely of its axis to torni a body portion and a nut-locking portion relatively movable, and a screw operatively engaging said portions and adapted to move them relatively to lock the nut against turning movement on the post.

Signed at Chicago this 8rd day of April,
